Someone claiming to have seen the Captain America sequel already has just announced the film's post-credits scene. It comes from an odd source, but the description still sounds pretty plausible to me. Either way, warning: After the jump is a significant spoiler or a pack of lies.

The news comes from Lainey Gossip, whose writer apparently has access to secret early Marvel movie screenings (which seems unlikely, but in her article she describes both the film's abundance of physical stunt-work, as well as the characters of both Peggy and Sharon Carter which leads me to believe the writer is legit). Anyways, here's her description of the scene:

But the thing that's probably going to leave people talking the most is the post-credits stinger. They're calling them "The Twins", the brother-sister team of Quicksilver and the Scarlet Witch, and they don't look like any Marvel heroes we've met to date. Having seen them, I am really sad for Fox and the X-Men, because this sh*t… is horrible in and of itself, but in comparison it's outright embarrassing.

Makes total sense to me. Of course Cap 2 would link to Avengers 2 instead of the goofier, cosmic Guardians of the Galaxy; besides, Marvel always loves introducing these types of characters in earlier movies when they have the chance; and I'm sure Marvel is cackling delightedly and essentially getting their Quicksilver and Scarlet Witch in theaters before Fox's X-Men: Days of Future Past.

And for the record, I think X-Men's Quicksilver is embarrassing with or without a comparison.
